LEVELING DEVICE FOR BILLIARDQ-TABLES.

Specification of Letters Patent. Patented O t 12 1920 Application filedNovember 24, 1919. Serial No. 340,172.

, for devices of this character wherein a supporting plate is providedadapted to be adjusted as to height by means of a plurality ofregulating screws. These devices how ever, are open to objections chiefamong which are that they are cumbersome, complicated, and difficult toattach and adjust by an inexperienced person, and further that in eachinstance the set screws are operated from the top wherein the head ofthe set screw protrudes to a disadvantage and the whole weight of thetable is on the point of the screw and the jar of the building or floorcauses a loosening of the screw and consequent settling at that point.

A further object of the invention is to provide a device of the abovementioned character wherein the adjusting elements are readilyaccessible.

A still further object of the invention is to provide such a devicewhich will be simple in construction, durable and cheap to manufacture.

A further object of the invention is to provide a device that can beplaced under the table leg by the most inexperienced person, in amodicum of time; and adjusted without a possibility of his injuring thetable top by having to raise the leg unduly.

Other objects and advantages will be apparent during the course of thefollowing description.'

In the accompanying drawings wherein for the purpose of illustration isshown a preferred embodiment of our invention, and wherein likereference characters are employed to designate like parts throughout thesame.

Figure 1 is a perspective of a portion of a billiard table leg showingour device applied thereto.

Fig. 2 is a section taken on theline 2-'-2 of Fig. 1. i

Fig. 3 is a perspective view of our device showing the parts separated.

F 1g. 4 1s a sectional view taken on the a line -14 of Fig. 2 showingthe manner in 1which the floor plate may be placed in posiion. 7

Referring now more particularly to the draw ngs the numeral 10 indicatesa rectangular tray or bearing plate provided with flanges 11, 12 and 13.I

. The fourth side 14 is open for a purpose herelnafter to appear. Theflange 11 or the flange upon the front side of the plate is providedapproximately centrally thereof with an outstanding portion 15. Theflanges 12 and 13 are provided adjacent the open side L1 of the platewith outstanding Y portions 16. These portions 15 and '16 are providedwith'scr'ew threaded apertures 17 adapted to receive screws 18. As moreclearly shown in Figs. 2 and 1, the heads of these screws are invertedand are below the plate and are provided at their lower ends with aconical portion 19.

A floor plate 20 is provided substantially U-shaped in form andaffording conical depressions 21 adapted to receive the conical heads ofthe screws 18. This floor plate may or may not be secured to the flooras is desired.

In applying the device to a table it is merely necessary to lift the legof the billiard table or the like the thickness of the plate 10 andslide the plate under the table leg open end first until the flange 11engages against the leg of the table when the table leg may be releasedto place its weight upon the plate, the plate then being in the positionshown in Fig. 4. The height of the outstanding portions 15 and 16 fromthe floor when the bottom of the bearing plate 10 is resting upon thefloor is sufficient so that when the screws 18 are fully elevated, asshown in Fig. 4, the plate 20 may be slid thereunder and placed inposition. Subsequently the screws may be tightened down to engage in theopenings 21 for a purpose of leveling the table.

It will be obvious that in placing our leveling device in position it isunnecessary to ra1se the leg of the table to such a height that itdistorts the body of the table 'sufiiciently to cause damage theretoandthat the plate is readily attached to the table (tr re- 'movedtherefrom. In actual use the {plate may bev covered by anysuitablemeans, or the outstanding portions 15 and 16 may be enlarged, assuggested by the dotted lines at V 22 upon Fig. 4, so that thescrews 18when fully elevated do not project above the upper surfaces'thereof inwhich case the cover plate will become unnecessary'.-

As many changes are possible in the de- Sign and shaping of the platesand in the particular arrangement thereof, we do not limit ourselves tothe specificstructure herein shown, but mayfmake'any such changeswithout departing from the spirit of the invention, or the scope of thesubjoined claims. IV hat we claim is 1. In a leveling device for gametables, a

plate adapted to receive a leg of the table, said plate being suppliedupon the front and two sides thereof with upstanding flanges having outturned portions, whereby said plate forms 'a' socket having one openside, screw threaded openingsformed in said out turned portions,a'U-shapedfioor plate provided upon its upper side with depressionscorresponding in number and arrangement I to the screw threaded openingsin said out turned portions and screws extending through said threadedopenings and having their heads inverted and engaging in said recesses,the heads of said screws corresponding in contour to said recesses;

2. In a leveling device for game tables, a

plate adapted to receive a leg of the table, 7

said plate being supplied upon the front and two sides thereof 7 withupstanding flanges having out turned'portions, whereby said plate formsa socket having one open side, the out turned portion of the'fiangeupon, the front of said bearing plate being disposed centrally thereofand the out turned portions of said side flanges being disposed adjacentsaid open side, screw threaded openings formed in said out turnedportions, a U-shaped floor plate provided upon its upper side withconical depressions corresponding in number and arrangement to theWILLIAM A SABINS.
